I think this is hands down the best free addon available in the community. There are also other great free addons, but they might be not for everyone. But embedding media is essential to any forum, so anyone can profit from this addon objectively speaking as it covers a lot of sites. Thank you.

Really makes media embedding in posts, pop. Users really like the experience of being able to just post a link to almost any media, and it embeds when they submit their posts. The "Lazy Loading" feature is great too. Very nice add-on.
